FURRING DEVIGE.

Application filed April 11, 192

This invention relates to furringdevices adapted for securing a plaster supporting base, as metal lath, upon a wall or surface to be plastered and for similar purposes.

Stated generally, the object of the invention is to provide a furring devicefor the purpose specified, which will be simple in construction, elfective for its designed purpose, and which may be manufactured at relatively small cost.

A specific object ofthe invention is to provide improved and simplified means for initially securing said furring devicesto the studding or other supporting means, separate from the means for securing the plaster sup porting base or other structural material, to the furring devices. y

In accordance with my invention, fur-ring devices for ellecting the objects of the inventioncomprise stools, each comprising a portion supported in spacedrelation to the stud:- ding or other supporting surface by a depending flanged portion, the outer ends of which are adapted to rest againStsaid surface.

Furring stools embodying my invention and improvements also comprise the various features and details of construction hereinafter described and claimed.

In the accompanying drawings in which the invention is fully illustrated,

Fig. 1 is a top plan view of one furring stool of my invention;

Fig. 2 is a plan View showing said stools as applied in use for securing metal lath upon a wall or surface to be plastered;

Fig. 8 is a view from theright side of sf And Figs. lto 7 are views illustrating still another form of stool embodying my invention. v

Describing the invention with particular reference to the drawings and referring in the first instance, particularly to Figs. 1, 2 and 3, A designates a furring stool embodying my invention as a whole, comprising a flat marginal portion 1, a raised central portion 2 and an intermediate connecting portion 3. The raised central portion of the stool is provided with a hole or opening 4L adapted to receive a nail 5 for securingsaid fur-ring stool to the studding 6 of a wall or other surface to which plaster is to be applied.

As shown, a head 7 is formed on the nail 5 at adistance from its projecting outer end, say one-half to three-quarters of an inch.

ceive securing nails of desired size Serial no. 182,726.

The intermediate portion 3 of the furring stool, which connects the marginal. and raised central portions thereof may be skeletonized by forming holes 8 therein, said intermediate connectingportion thus consisting ofspaced sections. '7 My invention, however, conte1nplates continuous intermediate portions, if desired. I I

As shown, and in accordance with usual building practice, building paper or other insulating covering. 9 is applied to ding 6. p 1 I 1 r In securing metal lath or other sheet'material 10 to the studding 6, thefurring stools A are first secured to the studding 6 with their marginal surfaces resting in contact therewith or with the insulating covering 9, by means of the nails 5 which are inserted through the holes 4 inthe raised portions 2 of said stoolsand driven intothe studding until the heads 7 on the nails rest against vthe raised central portion 2 ofthe stool.

After securing said stools in position to the studding 6, the metal lath or other material is applied so as to rest in contact with the topsof the stools or, withthe heads7 of the nails 5, the projecting outer ends 5' of said nails extending through the holes or openings in said metal lath, or other material. 'After the lath or other material is applied, it is secured in position by bending the projecting outer ends 5 of said nails the studdownwardly against the outer side thereof,

1 as shown in full lines in Figs. 2 and 3.

As a modification ofthe invention, the

furring stools, instead of being stamped from relatively thin, light sheet metal, as sheet steel, as in the case of my improved furringstools heretofore described, said stools are made from sheet metal channels rolled from strips of sheet metal, preferably sheet steel, which is relatively much heavier and stronger than that used for making my improved furring stools heretofore described, and cut cross-wise into pieces of desired length. A desirable size for this form of furring stool is, approximately, width len th and hei 'ht and the can be O L) y manufactured at very low cost by cutting A channel bars, rolled from stock of approximately '16 gaugewhich can be purchased in quantities co1nmerciallyinto pieces ofdesired length and piercing the raised portions thereof with holes adapted to reably nails having heads formed at a distance prefer from their outer ends, as in the case of the stools'shown in Figs. l to 3. Also, where building paper or other insulating covering is to be used, which might be penetrated or torn by the edges of the depending portions of said stools when the projecting outer ends 7 of the securing nails are bent over against the outer side of the metal lath or other material, washers of thin metal, preferably tin, are preferably inserted between said stools and the building paper or other insulating covering, which will operate to distribute the pressure of said stools and thus prevent them from tearing or penetrating said building paper or other material, in an obvious manner.

Describing said modification with reference to the drawings, A designates the furring stool as a whole, comprising a portion 2 formed at the edges of which are margina flanges 17, the outer edges of which are adapted to rest in contact with the studding 6*, either directly, or where building paper or other insulating covering is used, as shown in Figs. 6' and 7 upon discs'18 of thin sheet metal, prete'ably tin, inserted between the outer edges of the marginal flanges l7 and said insulating covering.

Each of the stools A is pierced approximately at the center-t its raised portion 2 with a hole '8 adapted to receive a nail for securing said stool and also the metal lath or other material to the studding, said nails as shown being similar to those shown in Figs. 1 to 3, having heads 7 formed at a said stools, said stools and securing means forming separate parts.

2. Furring comprising stools as specified in claim 1, in which the seat portions of the stools are provided with holes and the securing means consists of nails driven into the supporting surface through the holes in said seat port-ions, heads formed on said nails at a distance from their outer ends providing means for separately securing said stools to the supporting surface, and the outer ends of said nails when bent laterally forming means for securing sheet material to said stools.

3. Furring as specified in. claim 2, in which the furring stools consist of short lengths of metal channel bars secured to the support ing surface with the channels thereof disposed inwardly. g

In Witness that I claim the foregoing as my invention, I aillx my signature this 6th day of April, A. D. 1927.
